This is a brief howto for configuring the wpa client on voyage (0.40) based on my experience with the Cisco Cardbus Adapter (AIR-CB21AG-W-K9) running firmware mac 5.6 phy 4.1 radio 3.6.

After you update your configuration files, to bring up the wireless card:
====== Commands ======
**ifup** ath0\\
#wpa_supplicant will start and try to bring up network 0 (in this example "wpa).
 you'll need to supply an identity and password if you are using PEAP like 
 the example.  replace {userid} with your userid, {password} with your password.\\
 **wpa_cli identity 0 ** {userid}\\
 **wpa_cli password 0 ** {password}\\
 # to check on the connection use:
 ** wpa_cli status verbose**\\
 # to change to another network use:\\
 **wpa_cli select_network 1**\\
 **wpa_cli identity 1 **{userid}\\
 **wpa_cli password 1 **{password}\\


====== Troubleshooting notes: ======


I have seen a problem using the ifup command regarding RO file system (haven't tracked
it down yet -- may be specific to my system only) - if so, remountrw then try runing the
ifup command again. 

If you want to see the detailed debugging information, kill any running wpa_supplicant
and start one with debugging.  

/sbin/wpa_supplicant -dddd -P /var/run/wpa_supplicant.ath0.pid -i ath0 -D wext -c /etc/wpa_supplicant/conf -C /var/run/wpa_supplicant >/tmp/wpa-dddd.txt


=Example file: /etc/wpa_supplicant/conf
Note: ap_scan=2 allows your client to see ssids that are not broadcast.

ctrl_interface=/var/run/wpa_supplicant
ap_scan=2

network={
        id_str="wpa"
        ssid="wpa"
        key_mgmt=WPA-EAP
        eap=PEAP
	pairwise=TKIP
	group=TKIP
	proto=wpa
        }

network=(
	id_str="leap"
	ssid="leap"
	key_mgmt=IEEE8021X
	eap=LEAP
	}

network={
	id_str="wpa2"
	ssid="wpa2"
	key_mgmt=WPA-EAP
	eap=PEAP
	pairwise=CCMP
	group=CCMP
	proto=RSN
	}
